Listed at the top are tools specialized for finance / quant data visualization only, More generic or python tools are at the bottom.
If the visualization you want is fairly generic (bar chart, pie chart, etc.) and small data sets, these generic tools will be the best solution as they have many users and a huge investment to make them work for many use cases. If however you want trade / finance specific visualiation e.g. Blotters, Order books etc. you will be better with a tool specialized for the job. These will however require either more work to configure and maintain or be costly.
